When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve 5a + 6a = -3a - 3z + 3 for a in terms of z.
| 2\(\frac{1}{5}\)z + \(\frac{3}{5}\) | |
| -1\(\frac{1}{8}\)z + \(\frac{3}{8}\) | |
| -1\(\frac{1}{3}\)z + 2 | |
| 3\(\frac{1}{3}\)z - 2\(\frac{1}{3}\) |
